[@FahimKhan-vd8yp]

If you've seen the first lecture,
please see all the 26 lectures and do the homework.
you'll be thanking me after finishing this series.
I just came back from 26th lecture to tell you not to give up, just finish it, it would take only 30 days with homework.

does he complete his whole book at the end?

how did you do the assigned readings since they are from the 1st edition and not second and 2nd edition is only available now ?

Oppenheim was a true pioneer. I am eternally grateful for his vision, and I’m grateful that MIT makes this excellent series freely available online.

One common example of the discrete time signals, in our days, is the COVID-19 graph depicting the number of cases for each day. -_-

why was the orchestra removed with the noise from the original recording after the processing? or was it on purpose?

As he says, it was a surprising consequence of some experimental non-linear processing.

Why are images an example of a continuous time signal as opposed to a discrete time signal? Don't we have a mapping between discrete pixels and brightness / RGB values?

[@charismaticaazim]

Images would typically be represented by discrete signal. What made you call it as a continuous signal.
